Lagg has swapped sherry for American oak. The new Lagg Quarter Cask Small Batch is a heavily peated (50ppm) single malt from the south of the Isle of Arran, fully matured for six years in 125-litre quarter casks rebuilt from ex-bourbon barrels. It is bottled at 56% ABV, non-chill filtered and at natural colour, with an RRP of £81.95. It is the third Small Batch from Lagg to be released worldwide, following the Palo Cortado Small Batch in 2025 and the Manzanilla Sherry Finish earlier this year, and it is on shelves now at specialist retailers in selected global markets.

Two sherry-led releases told us how Lagg’s spirit behaves with rare fortified-wine casks. This one strips that back and asks a simpler question: what happens when you give six-year-old peated Lagg nothing but small, active American oak?

What is the Lagg Quarter Cask Small Batch?

The Lagg Quarter Cask is the latest entry in Lagg’s Small Batch series, a run of limited bottlings that sits alongside the distillery’s permanent core range. Where the core whiskies show the house style, the Small Batch releases are where Lagg tests how its heavily peated spirit responds to a specific cask.

The first two worldwide Small Batches were both about sherry. The Palo Cortado Small Batch (2025) and the Manzanilla Sherry Finish (2026) each took bourbon-matured Lagg and finished it in rare sherry casks. This third release goes the other way, with no finish at all. The label reads “Fully matured in Quarter Casks”, and that is the whole story of the wood.

Distillery Manager Graham Omand selected the casks himself, and his summary of the result is short: “The quarter casks bring all of the flavours we know and love into sharper focus.”

Why quarter casks change the whisky

A quarter cask holds around 125 litres, a little over half the volume of a standard American oak bourbon barrel. Shrink the cask and you increase the ratio of wood surface to spirit, so more of the whisky is in contact with the oak at any given moment.

In practice, that means the vanilla, coconut, caramel and spice that American oak gives up arrive faster and in a more concentrated form. Lagg’s quarter casks were rebuilt from former bourbon barrels, so the staves carry that sweet, toasty bourbon-oak character into a smaller space.

Six years is a meaningful stretch in a cask this size. Pair it with 50ppm spirit and 56% ABV, and you have a whisky built around intensity: oak and peat both turned up, with nothing in between to soften the edges. The distillery says the vanilla, citrus and oak spice sit around ashy smoke, while the oily character that defines Lagg stays at the core.

Who is Lagg Distillery?

Lagg is the second distillery of Isle of Arran Distillers, the company behind the Arran single malts made at Lochranza in the north of the island since 1995. Groundwork at Lagg, on the southern tip of Arran near Kilmory, began in 2017, and the distillery took its first spirit cut on 19 March 2019.

From day one, Lagg was set up to make heavily peated whisky, which frees Lochranza to focus on its largely unpeated house style. Lagg’s spirit is distilled from Concerto barley peated to 50ppm, and the distillery has stuck to that recipe from its Inaugural Release batches onwards.

For readers outside Scotland: Arran sits in the Firth of Clyde, off Scotland’s west coast. Officially, its whiskies fall under the Highland region in the Scotch Whisky Regulations, but they are almost always grouped with the “Island” malts on shelves and in conversation. Lagg’s permanent range is built around the Kilmory Edition and the Corriecravie Edition, which show the spirit through different maturation styles.

Is the Lagg Quarter Cask worth £81.95?

For a six-year-old, cask-strength, heavily peated single malt that is non-chill filtered and fully matured in small casks, £81.95 sits squarely in the price band for limited peated releases at this strength, and the specification earns it.

This is a bottle for peat drinkers who like their whisky at full strength and want to see what concentrated American oak does to a smoky spirit. It is also the clearest look yet at Lagg’s spirit with nothing borrowed from a sherry cask, which makes it essential for anyone following the distillery from its Inaugural Releases onwards.

If what drew you to the Palo Cortado or Manzanilla Small Batches was the fortified-wine richness, set expectations accordingly: this release is about vanilla, citrus, pepper and smoke, not dried fruit. For everyone else curious about where Lagg is heading, this is the one to open next to the Kilmory Edition and taste the difference six years in small oak makes.

The palate is oily and full-bodied, with vanilla fudge, earthy smoke, cracked black pepper, grilled lemon and toasted coconut. The finish is long and smoky, turning saline before vanilla and citrus return.

What is a quarter cask in whisky? A quarter cask is a small oak cask holding around 125 litres, roughly half the size of a standard bourbon barrel. The smaller size puts more of the spirit in contact with the wood, so oak flavours such as vanilla, coconut and spice develop faster and more intensely. Lagg’s quarter casks were rebuilt from ex-bourbon barrels.

Is the Lagg Quarter Cask cask strength? Lagg bottles the Quarter Cask Small Batch at 56% ABV, without chill filtration or added colour, and retailers list it as cask strength. At that strength it rewards patience: taste it neat first, then add a few drops of water to open up the citrus and orchard fruit under the smoke and oak.
